CHARLES A. GEIGER, JOHN F. ECCARD, AND RICHARD H. SOTHERLAND, J R., OF TROY, OHIO,

ASSIGNORS TO TROY WAGON WORKS COMPANY, TROY, OHIO, A CORPORATION OF OHIO.

To all whom 'it may concern:

Be it known that we, CHARLES A. GEIGER, JOHN F. ECCARD, and RICHARD H. So'rHE'R- .LAND, J r., citizens of the United States, re-

siding at Troy, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Reversible Dump wagons, of which the following is a speci cation.

' Our-invention relates to dump wagons and particularly bottom dump wagons.

Our object is to construct a reversible dump we on and by that we mean a wagon that can e moved or drawn "either frontwards 'or backwards, and one that can be most advantageously used ina series coupled together.

It is now common practice to couple a series of dump wagons, constituting a train and operate this train by motive power such as a traction engine for hauling purposes. In operating a train of dum wagons, as just mentioned, it is obvious tiat it is very desirable to reverse the direction of movement of the train of dump wagons in order to avoid the necessit of turning the entire train of wagons, as or instance if the wagons are hauling dirt or other excavating material from a loading point to a dumping point. Our construction is such that a single dum arrange wagon with the improvements'as in our inventlon can be readily used in places where it is desirable that a single wagon be backed out of the blind alley or other diflicult places to enter, and when the wagons are coupled together as a train, the entire train 'of wagons can be pulled backwards by uncoupling the engine furnishing the motive power from the front thereof and while' the engine is being moved to the rear of the train the couplings and connections for the train of dump wagons can be quickly and readily shifted so that when the engine is coupled to the rear end of the train, the entire train of wagons can be returned to the starting point.

3 is a rear view t ereof. Fig. 4 is a front view. Fig. 5 is a 'plan view of the front running ear. Fig. 6' is a sectional view of the whee spindles and bearings therefor.

therefor. Fig. 9 is a sectional view on the line as w of Fig. 8. Figs. 10, 11,- and 12 are detail views of the eccentric device for changing the gather of the spindles or wheels. Figs. 13 and 14- are detail views of the collar and linch pin for the wheels.

Like parts are represented by similar let ters of reference in the different views.

The wagon bed is indicated by the reference letter (1, having the ordinary hinged bottom portions indicated by a. The general construction of the dump wagon is that in common use at the present time, bein so arran ed that the bottom can be readily opene nections, as arran ed in our improved dump wagon, are such t at there canbe no interference with this dumping o eration. The

wheels of the'wagon are in icated by the,

numeral 1. We have shown the front and to discharge the load, and the con rear axles, a (1 (see Fi 2) preferably of inner portion of the spindle is perforated and is formed with vertical bearings whichcooperate with seats in the bifurcated parts of the axle to permit a lateral swinging movement of the spindles. The trunnion, 0,, extends through the erforations in the end portion of the spindle and through the bifurcated ends of the axle, the parts being bolted together so that the trunnion constltutes a pivot for said swinging spindle. Each spindle is formed with an arm a which projects therefrom (see Figs. 2 and 5) and the arms of the spindles are connected by bars a" a. These conneetin bars are disjointed-and at their free on s are operated by eccentrics a (Figs. 10-11-12) and the eccentrics a are controlled by the hand lever. a the lower end of which fits into a socket which is sup orted by brackets extending from the draft In our construction of axles, spindle, draft .bar and connecting bars our object is to so arrange the parts that by operating either the front or rear draft bar the wagon can be ars of the wagon.

front or rear movement. This adjustment of the s indles can be readily made by turning the and lever while the engine or other device furnishing the motive power is being uncoupled from one end of the train of wagons and moved to the 0 posite end, it

being understood, of course, t at each-wagon will have to be adjusted in this respect for adaptin it to the changed direction in movement. hen the train of wagons is moving in a normal direction, a. e. the front of the first wagon in the train coupledto the traction engine, the front draft bar on each wagon will be free to swing laterally and thereby guide each wagon each rear draft bar being held rigid during this movement so as to prevent all lateral swinging movement of the rear wheels, but when the direction of movement of the wa on is reversed, the front draft bar wil be made rigid so that the front wheels can no longer swing laterally and the rear draft bar of each wagon will be released from its rigid connections so-as to ermit the rear wheels to swing laterally Whlle the train of wagons is beingdrawn in a reverse direction. For

this reason we have shown the front and.

rear draft bars I) pivotally secured at b to the axle of the wa on. The front draft bar I) (see Fi s. 7 an 8) is pivotally secured between t e bolster and t e axle a, there bein a sleeve indicated by the numeral 2 whic fits over the king bolt 6 and this secured rigidl By releasin t e pin 3, the draft bar becomes disconnects sleeve 2 is of such dimensions that the draft bar I) swings freely upon the sleevebetween tongue to the wagon.

[The disconnecting means for the draft bars -is as follows: An openin b which, when the draft bar is to be hel rigidly secured to prevent any swinging lateral move-' ment of the wheels, registers with an opening 6 which is formed in a plate 12 secured to the bed a of the wagon and a pin 3 (Fig. 7) can' then be inserted throu h the'o en ings b b and thereby the dra bar wiil be to the bed of the machine.

and can then be used as a draft appliance for guiding the wheelsto which it is connected, and his to be remembered that the adjustment in the ather of the wheels by operating the hand ser a can readily be made so as -to' adjust the wheels for a change in the direction of movement of the wagon. I

" Further explaining the construction of the rocking bolster, heretofore referred to, it will become apparent that in this construction of a dump wagon it is especially desirable that one of the axles should have a limited vertical movement independent of the bed to prevent any straining or twisting effect that would otherwise occur when the wheels of the wa on were traveling over uneven surfaces. or this reason and for other reasons we employ two rocking bars shown clearlyin Figs. 1 and 8. The rocking bar a is secured to the front axle by the king bolt 5 heretofore referred to, and the rocking bolster securely supports the bed a as shown in Figs. 3, 4,and 1 so that the bolster and axle will work independently of each other. The ends of the bolster c extend between plates or guides .0 and 0 and bolted rigidly to the bolster 0, and these plates or guides being rigidly attached to the bolster a project downwardly on either side of the axle a, (Fig. 8) allowing the bed a' and bolster to work in unison and the axle a to work independently of the bed a and bolster c as shown in Figs. 8 and 9. The other rocking bar 0 lies at the extreme front of the Wagon bed and the rocking bar is pivotally secured to the bed a by a pivot c" (seeFig. 4:) and the ends 'of the rocking bar also project between rigid plates or braces c and 0* (Figs. 1 and 4) projecting from the bed (1. Attached rigidly to the plates 0", c are braces not lettered extendingl backwardly to the plate 0. Attached to t e bottom of the bar a (Fig. 1) are braces 0 extending downwardly and backwardly to the axle making a rigid connection between 0 and (1 and making a very strong construction of the front axle, while permitting a very desirable vertical movement of the axle and front bar 0 independent of the bed.

In order to prevent the wheels from working loose from the spindles when the direc tion of the movement of the wagon is reversed we have shown collars 0 (see Figs. 6 and 13) which fit on the free end of the spindles and are held thereon by linch pins,

0, in theordinar or usual way. In order to ad ust the m es we have shown an adjustable clam ing device 4. of any ordinary.

construction see Fig. 9).

Having described our invention we claim as follows:-- I 1. In a dump wagon, the combination-of front and rear axles with the bed for said wagon, a plurality-"of independent rocking bolsters for the front axle, and means for 3 connecting said'a-xle to one of said rocking bolsters, substantially as specified.

2. In a reversible dump wa on, the combination of a wagon bedwith ront and rear axles, a rocking bolster for the rear axle, and a lurality of rocking bolsters for the front ax e, means connecting the front axle with one of said rockingbolsters, and means for connecting the bed of said wagon with other rocking bolster, substantially as specified.

3. In a reversible dump wa on, the combination of a wagon bed with ont and rear axles including pivoted spindles, front and rear draft bars plvotally secured to their corresponding axles, connectionsbetween each draft bar and their corresponding spindles, wheels for said spindles and means for changing the gather of said wheels inde pendent of the movement of the'draft bars, and means for disconnecting each of said draft bars from said wagon bed, for the purpose specified.

4. In a reversible dum wagon, the combination of wagon bed WltlhflODt and rear axles including pivoted spindles, front and rear draft-bars pivotally connected to each axle, a plurality of rocking bolsters for the front axle, one of said bolsters being located forwardly of the other, and the front draftbar being pivoted between the axle and the rearmost rocking bolster and extending forwardly below the front rocking bolster, sub-,

stantially as specified.

. 5. In a reversible dump wagon, the oom- Bination of front and rear axles includin spindles with the bed for said wagon, and connections between the spindles and draftbars, a plurality of rocking bolsters for one of said axles, a lvotal connection for one of said draft-bars tween the axle and rocking bolster, said draft-bar extending below the other rocking bolster, and means for connecting the axle with said last mentioned rocking bolster, substantially as specified.

6. In a reversible dump wagon, the combination of front and rear axles including pivoted spindles, a plurality of rocking bars for the front axle, one of said rocking bars being located forwardly of the axle and a brace extending from said axle to said last mentioned rocking bar, for the purpose specified.

In testimony whereof, we have hereunto set our hands this 3rd day of February 1908.
